Classic Bootstrap

In classic bootstrap addons, you don't set a default. Firefox automatically figures out the closest locale between the users browser and from whatever locales your addon has.

JPM

Are you doing a JPM/SDK addon? If you are localizing the preferences, you have to initially set a string in the package.json:

"preferences": [
    {
        "name": "imagePath",
        "type": "file",
        "value": "",
        "title": "Image File Path",
        "description": "A path to an image on your computer that the dock icon should be set to"
    },
    {
        "name": "restoreDefault",
        "type": "control",
        "title": "default locale:Restore Default",
        "description": "this is from package.json:: If you have changed your icon, and want to restore the default Firefox icon, click this button",
        "label": "this is from package.json:: Restore"
    }
]

So the default is whatever you set there. If firefox cannot find a match to the locales provided it will use the string from package.json.

So for exmaple to localize the restoreDefault strings you would create a en-US.properties file and drop it in a folder named locale like this:

restoreDefault_title=blah Restore Default blah
restoreDefault_description=blahIf you have changed your icon, and want to restore the default Firefox icon, click this buttonblah
restoreDefault_label=blahRestoreblah

So now set your browser locale to english by going to about:config and then change the preference general.useragent.locale to something other then en-US (change it to es) for this example then load your preferences page (may need to restart browser after changing general.useragent.locale). Now because your addon does not have es.properties you will see the strings from package.json. Set your general.useragent.locale back to en-us and then restart your browser, and go back to your addon pref page, and you will see the strings from the properties file.
